Ok I understand a little now. First is the max wingloading of 115g/dm2 . That works out to about 37 oz/sqft. That makes sense and is understandable, however it then goes on to say that wingloading applies only to gliders that are scaled to 1/3 scale. All others will have a correction factor applied...then doesn't say what the correction factor is.

Lastly it states that under no circumstances will the weight of the glider exceed the number that is derived from a rather strange formula. There's no units in the formula so I assume the units for wing area are dm2 and the end result will be in kg. I don't know the numbers for your ship but it would be handy for you to know your max weight allowed so you can design in the strength that you want and know that you won't have your dream ship disqualified due to weight.

It will likely end up too light if anything. I've already designed in provisions for ballast to bring the wing loading up to maximum.

I'm building the stretched ASW22 DB (28 meter) version so I get a bit more area.......

I saw that but one quick attempt using Ms Google to find the wing area didn't reveal what the area might be for the stretched version. Given your 25 foot span and 30+ oz wingloading I can imagine the excitement a ship like yours would be. I wanted to see a ball park for how much weight that you have to work with. My guess is that given the spars and nose weight that you're going to need for this size of a ship that you are likely going to be in the 25 to 30 pound empty weight to begin with even before ballast. Hopefully Santa has plenty of carbon fiber headed your way this year.
